The range check for the CPUCFG ID is wrong (should have been a || instead of &&) and useless in effect, so fix the obvious mistake. Furthermore, the juggling of the temp return value is unnecessary, because it is semantically equivalent and more readable to just return at every switch case's end. This is done too to avoid potential bugs in the future related to the unwanted complexity. Also, the return value of _kvm_get_cpucfg is meant to be checked, but this was not done, so bad CPUCFG IDs wrongly fall back to the default case and 0 is incorrectly returned; check the return value to fix the UAPI behavior. While at it, also remove the redundant range check in kvm_check_cpucfg, because out-of-range CPUCFG IDs are already rejected by the -EINVAL as returned by _kvm_get_cpucfg(). Fixes: |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
